This dissertation is a study of the effect of Texas's charter high schools on diploma graduation and General Educational Development (GED) attainment. Utilizing data from the Texas Schools Project at the University of Texas at Dallas, the study follows a cohort of Texas students enrolled as 10th graders in the fall of 1999 and tracks their graduation outcomes through the summer of 2002 when they were expected to have completed high school. The analysis uses case study research and probit regression techniques to estimate the effect of charter school attendance on graduation and GED outcomes as well as the effect of individual charter school characteristics on charter students' graduation outcomes. The study's results indicate that charter school attendance has a strong negative effect on diploma graduation and a strong positive effect on GED attainment. In addition, the study finds that charter schools that offer vocational training, open entry/exit enrollment options, and charters that are operated in multiple sites or "chain" charters have positive effects on charter students' diploma graduation outcomes. Charters that offer accelerated instruction demonstrate a negative effect on diploma graduation. The study finds that charter school graduation outcomes improve as charters gain experience and that racially isolated minority charter schools experience reduced graduation outcomes. The study's results also indicate that Texas's charter high schools may be providing district schools with a means through which to offload students who may be difficult to educate. The analysis finds that districts may be pushing low-performing high school students with attendance and discipline problems into charter schools in order to avoid the effort of educating them and to improve district performance on accountability measures related to standardized test scores and graduation rates. This finding suggests that that competition from charter high schools will not provide much incentive for districts to improve their programs, undermining a central premise of school choice initiatives.

This research investigated changes in self-esteem and whether the origin and development of that self-esteem could be described in adult females participating in a GED program located at an Army Community Outreach Center. The Coopersmith Self-Esteem Inventory was used to measure the self-esteem of 22 female family members of military personnel who did not adequately complete a high school program in the United States. Data were collected through interviews, daily journal writings, questionnaires, instructor's written observations, and the Coopersmith Self-Esteem Inventory.

K-12 schools are more commonly using online learning to supplement traditional classroom learning. Previous online adult education researchers have found no significant differences between traditional and online learning outcomes. However, little research has been done with regard to online General Educational Development (GED)-level learning for adults. The purpose of this quantitative study was to explore the effect of the Skills Tutor program compared with traditional learning on GED student achievement in reading/language arts. The Skills Tutor program was used as a means to address the low GED graduation rates at an adult education program through Memphis City Schools. This research was based on the constructivist learning theory. The research question examined the effect of an online skills program on English/language arts scores among GED students. Scores from the pretests and posttests of 40 adult education students were analyzed using analysis of covariance (ANCOVA) to determine statistical differences between 2 groups. One group (n = 20) received the intervention of the online skills program, Skills Tutor, along with traditional instruction, whereas the other group (n = 20) received traditional instruction delivered by the teacher only. The results indicated the traditional group's adjusted mean scores were significantly higher than the Skills Tutor group scores. Recommendations included additional research with larger samples of students, for a longer period, and focused on the fidelity of implementing of the Skills Tutor program at the local site. Implications for positive social change include providing research findings to the local administration on the current GED program and recommendations for continued research on the instruction that best supports adult learning.

Ce travail de thèse a porté sur la détection et localisation de défauts dans les réseaux de distribution HTA par les<br />indicateurs de passage de défaut (IPD). Les études ont été effectuées dans le cadre du développement attendu et<br />croissant des GED (sources de Génération d'Energie Décentralisées).<br />La première partie du mémoire est consacrée à l'analyse du comportement des IPD. En ce qui concerne<br />l'influence du contexte de fonctionnement sur la réponse des IPD, une partie est destinée à vérifier le<br />fonctionnement des modèles IPD développés et les règles d'utilisation des IPD prévus. Une autre analyse<br />l'influence des GED sur l'utilisation des IPD sur la détection et localisation de défauts. Pour l'amélioration de la<br />robustesse du diagnostic avec IPD en présence de fausses indications, une méthode de détermination de la<br />section en défaut (limitée par des IPD) est proposée.<br />La deuxième partie du mémoire est consacrée à une méthode d'optimisation du placement des IPD dans les<br />réseaux HTA sur la base d'algorithmes génétiques. Nous avons défini différents critères pour l'optimisation ; ils<br />sont validés par un programme de calcul des indices de fiabilité. L'influence de la GED dans le départ HTA sur<br />le placement optimal des IPD est analysée en tenant compte du coût de l'énergie non fournie par la GED et du<br />fonctionnement envisageable comme un secours de la GED.

Value at Risk (VaR) and Expected Shortfall (ES) are methods often used to measure market risk. Inaccurate and unreliable Value at Risk and Expected Shortfall models can lead to underestimation of the market risk that a firm or financial institution is exposed to, and therefore may jeopardize the well-being or survival of the firm or financial institution during adverse markets. The objective of this study is therefore to examine various Value at Risk and Expected Shortfall models, including fatter tail models, in order to analyze the accuracy and reliability of these models. Thirteen VaR and ES models under three main approaches (Parametric, Non-Parametric and Semi-Parametric) are examined in this study. The results of this study show that the proposed model (ARMA(1,1)-GJR-GARCH(1,1)-SGED) gives the most balanced Value at Risk results. The semi-parametric model (Extreme Value Theory, EVT) is the most accurate Value at Risk model in this study for S&P 500. / October 2014

Les politiques entreprises dans le domaine de la production d’électricité pour lutter contre le changement climatique reposent communément sur le remplacement des moyens de production fossiles et centralisés par de nouveaux moyens de type renouvelables. Ces énergies renouvelables sont en grande partie distribuées dans les réseaux moyenne et basse tension et sont le plus souvent intermittentes (énergies éolienne et photovoltaïque principalement). Les gestionnaires de réseaux s’attentent à ce que ce changement de paradigme induise des difficultés conséquences dans leurs opérations. Les mondes de la recherche et de l’industrie se sont ainsi structurés depuis le milieu des années 2000 afin d’apporter une réponse aux problèmes anticipés. Cette réponse passe notamment par le déploiement de technologies de l’information et de la communication (TIC) dans les réseaux électriques, des centres de contrôle jusqu’au sein même des moyens de production distribués. C’est ce que l’on appelle le Smart Grid. Parmi le champ des possibles du Smart Grid, ces travaux de thèses se sont en particulier attachés à apporter une réponse aux enjeux de stabilité en fréquence du système électrique, mise en danger par la réduction anticipée de l’inertie des systèmes électriques et la raréfaction des moyens de fourniture de réserve primaire (FCR), auxquels incombent le maintien de la fréquence en temps réel. En vue de suppléer les moyens de fourniture de réserve conventionnels et centralisés, il a ainsi été élaboré un concept de coordination de charges électriques délestables distribuées, qui se déconnectent et se reconnectent de manière autonome sur le réseau au gré des variations de fréquence mesurées sur site. Ces modulations de puissance répondent à un schéma préétabli qui dépend de la consommation électrique effective de chacune des charges. Ces travaux ont été complétés d’une étude technico-économique visant à réutiliser cette infrastructure de coordination de charges délestables pour la fourniture de services systèmes ou de produits de gros complémentaires. Ce travail de thèse réalisée au sein des équipes innovation de Schneider Electric et du laboratoire de Génie Electrique de Grenoble (G2Elab), est en lien avec les projets Européens EvolvDSO et Dream, financés dans le cadre du programme FP7 de la Commission Européenne. / Climate change mitigation policies in the power generation industry lead commonly on the replacement of bulk generation assets by Renewable Energy Resources (RES-E). Such RES-E are largely distributed among the medium and low voltage grids and most of them are intermittent like photovoltaic and wind power. System Operators expect that such new power system paradigm induces significant complications in their operations. The communities of research and industry started thus to structure themselves in the mid-2000s in order to respond to these coming issues, notably through the deployment of Information and Communication Technology (ICT) in power systems assets, from the Network Operations Centers (NOCs) down to Distributed Energy Resources (DERs) units. This is the Smart Grid. Among the range of possibilities of the Smart Grid, this Ph.D work aims in priority to provide a solution to handle the issue of frequency stability of the power system that are endangered by the combined loss of inertia of the power system and the phasing-out of conventional assets which used to be in charge of the maintain of the frequency in real time through the supply of Frequency Containment Reserve (FCR). The concept developed lead on a process of coordinated modulation of the level of loads of DERs, whose evolve depending on the system frequency measured in real time on-site. The strategy of modulation of each DER follows a pattern which is determined at the scale of the portfolio of aggregation of the DER, depending on the effective level of load of the DER at normal frequency (i.e. 50Hz in Europe). This work is completed by a cost benefit analysis that assesses the opportunity of sharing of the previous infrastructure of coordinated modulation of DERs for the supply of ancillary services and wholesale products. This thesis conducted within Schneider Electric’s Innovation teams and Grenoble Electrical Engineering Laboratory (G2Elab) is linked with the European projects Dream and EvolvDSO, and funded under European Commission’s FP7 program.

This thesis is a development of the theories presented by Carl Jung, Joseph Campbell, and Bruno Bettelheim concerning archetypes, the anima/animus concept, the Hero Cycle, and identity development through fairy tales. I argue that there are vital rites of passage missing in Anglo-Saxon culture, and while bibliotherapy cannot replace them, it can help adolescents synthesize their experiences. The theories of Jung, Campbell, and Bettelheim demonstrate this concept by defining segments of the story and how they apply to the reader. Because of the applicability, readers, despite their age, can use the examples in the book to help reconcile their own experiences and understand life as it relates to them. The works I examine include J.K. Rowling's Harry Potter series, Orson Scott Card's Alvin Maker series, J.R.R. Tolkien's The Lord of the Rings, Ursula K. Le Guin's Earthsea trilogy, and David Eddings' Belgariad. Though it is impossible to test the effects of reading such works on readers, the possibility of those effects exists. Bettelheim's work, The Uses of Enchantment, discusses similar themes and he provides scientific support through his use of anecdotal evidence. Following his example, I have tried to include evidence from my own life that exemplifies the effect reading epic fantasy has had on me. The aspects of epic fantasy in relation to going through adolescence I examine include the concept of responsibility and its relation to progress and maturity; gaining a social identity; and reconciling oneself to the dark side within and without, in society. These aspects are found within the superstructure of the Hero Cycle and the actions and motivations of the characters—archetypes—within the cycle. They are also present in real life and necessary concepts to understand to be accepted into society as a mature contributor.

This dissertation analyses the protagonists in The Dispossessed, The Left Hand of Darkness, and Tehanu by Ursula K. Le Guin, and looks at the extent to which they confront the Jungian archetype of the anima. I demonstrate that individuation and wisdom are not achieved in these characters until they confront the anima archetype within their individual psyches. I analyse the experiences and behaviour of each protagonist in order to identify anima confrontation (or lack thereof), and I seek to prove that such confrontation precipitates maturity and wisdom, which are goals of the hero's journey. The essential qualities of the anima archetype are wisdom, beauty and love. These qualities require acceptance of vulnerability. I argue that the protagonist is far from anima integration when he displays hatred and fear of vulnerability, and conclude that each protagonist is integrated with the anima when wisdom, beauty and love are evident in his character. / English Studies / M.A. (English)
